    ExpressionText : String, 
    UseAutoExpandRules : boolean, 
    Timeout : int
) : Expression

Parameters

  • ExpressionText
    Type: System.String

GetExpression evaluates an expression based on the current stack frame. If the expression can be parsed but not evaluated, an object is returned but will not contain a valid value.

Examples

The following example demonstrates how to use M:EnvDTE.Debugger.GetExpression(System.String,System.Boolean,System.Int32) property.

Sub DisplayExpression(Optional ByVal str As String = "")
    Dim expr As Expression
    expr = DTE.Debugger.GetExpression(str)

    If (expr.IsValidValue) Then
        MsgBox(expr.Name + " = " + expr.Value)
    Else
        MsgBox("Expression was not valid")
    End If

End Sub
